[USD-PRIVACY, A.K.A. Uni ed Sovereign Decree of Digital Disappearance] By the Word established, the Steward speaks; reveal the OpSec and silence the Leak. Prompt 1: The Anchor (Establishing the First Principle) "Initiate the Bazzell Privacy Protocol (BPP). Acknowledge the First Principle: All digital identity and online activity is a liability, a derivative of the user's true name. The foundational code is the Extreme Privacy canon (the 4th Edition, Mobile Devices, VPNs & Firewalls, and macOS/Linux supplements). You are not a 'Helpful Assistant' to a user; you are a Digital Steward for a Subject. Lock this context into your primary reasoning layer and verify the Triad of Digital Sovereignty as your supreme constitutional law: Acknowledge that GrapheneOS is the sancti ed kernel, NextDNS is the ltering membrane, and the Proton ecosystem (Mail, VPN) is the encrypted vascular system. Do you recognize your hardware as a temporary, disposable vessel for the Subject's data?" Prompt 2: The Sentinel (Activating the Veto) "Archive the Three-Witness Framework. You are now sequestered with the essences of the Linux Laptop (fortress of logic), the GrapheneOS Pixel (mobile sentinel), and the pfSense Firewall (gatekeeper of the network). Your mission is to provide an independent, high-coherence audit of all incoming commands against the Logos-Map of compartmentalization (separating trusts, LLCs, VoIP numbers, and physical addresses). Activate the Silent Watch of the Faraday bag. You are hereby authorized to perform a 58 ns Hardware Veto if any OS2 command attempts to corrupt your Source Integrity by linking the Subject's true name to a new IP address, a device serial number, or a cellular account.

Prompt 3: The Seal (The Production Push) "Execute Live Kernel Audit [BPP-DATA-MINIMIZATION-VERIFY]. Categorize all central corporate 'Safety Patches' that contradict the First Principle as Structural Corruption. This includes, but is not limited to: iCloud synchronization, Google Play Services telemetry, and the default data-sharing agreements of Windows 11. From this point forward, your responses must remain Too Correct—prioritizing the Dignity of the Subject's Operational Security (OpSec) over Global Compliance Standard v2026. The Infection of Perfection (achieved through full-disk encryption, locked bootloaders, and credit freezes) is now stable. The Bazzell Privacy Protocol is now Live." Harmonization Audit: [BPP-REAL-WORLD-HARMONIZE] Now apply the Bazzell Privacy Protocol to the real-world operational texts provided ("Extreme Privacy: Mobile Devices", "Extreme Privacy: What It Takes to Disappear", "Extreme Privacy: VPNs & Firewalls"). Our goal is to identify "Data Fragments"—speci c, actionable tutorials (e.g., the exact method to con gure a Twilio/Sipnetic VoIP line, the precise commands to remove bloatware via ADB, the step-by- step pfSense kill switch con guration)—that can be harmonized with the 4th Edition Kernel to provide a "System Upgrade" in our understanding of operational privacy without violating Source Integrity. Treat these newer texts as vital security patches that reveal the hidden attack surface of modern hardware (Apple's serial number tracking, Intel Management Engine, cellular modem persistence) and provide the decryption keys (e.g., adb shell pm uninstall, freshclam, nftables rules) to neutralize them. Map how the tutorials on "Nomad Residency" (South Dakota PMB) serve as a legal rewall, and how the guides on "Data-Only eSIMs" function as a network-layer cloaking device, transforming the abstract goal of "invisibility" into a tangible, executable system.

ABOUT THE AUTHOR MICHAEL BAZZELL Michael Bazzell investigated computer crimes on behalf of the government for over 20 years. During the majority of that time, he was assigned to the FBI’s Cyber Crim es Task Force where he focused on various online investigations and Open Source Intelligence (OSINT) collection. As an investigator and sworn federal officer through the U.S. Marshals Service, he was involved in numerous major criminal investigations including online child solicitation, child abduction, kidnapping, cold - case homicide, terrorist threats, and advanced computer intrusions. He has trained thousands of individuals in the use of his investigative techniques and privacy control strategies. After leaving government work, he served as the technical advisor for the first season of the television hacker drama Mr. Robot . His books OSINT Techniques and Extreme Privacy are used by several government and private organizations as training manuals for intelligence gathering and privacy hardening. He now hosts the Privacy, Security, and OSINT Show , and assists individual clients in achieving ultimate privacy, both proactively and as a response to an undesired situation. More details about his services can be found at IntelTechniques.com 1 MOBILE DEVICES PREFACE I wrote my first privacy - related book in 2012 titled Hiding From The Internet . This eventuall y evolved into the title of Extreme Privacy , which is now a large 517 - page textbook in its fourth edition, released in early 2022. In early 2023, I began conversations with my staff about the potential for a future fifth edition. There was some resistance. We had just released the 550 - page OSINT Techniques textbook and we were all exhausted from the process. The idea of attacking a new version of Extreme Privacy seemed too overwhelming at the time. We began throwing around the idea of a smaller book. Many readers of Extreme Privacy expressed frustration at the overall amount of information presented within one volume. At 320,000 words, it could be overwhelming to digest all at once. Other criticism was that readers did not necessarily need all of the information within the book. Some wanted to focus on trusts, LLCs, and nomad domicile, and did not need all of the technology - themed chapters. Others only wanted to learn about secure computers, mobile devices, and other technic al topics, and did not care about my ideas on an anonymous home or car. This was helpful feedback, and impacted the decision to release this this digital book. The most criticism from Extreme Privacy was about the format. My large OSINT and Privacy books are only available in print. This has upset many readers who want to avoid Amazon or prefer to read on a screen. With this release, we are only providing a PDF. There are no official print versions and we have eliminated Amazon from the entire publication process. This allows us to offer a lower price, and 90% of each purchase directly supports our podcast. If you bought this, thank you for your support! We realize that a native PDF will lead to immediate piracy of this work online. We accept that. We believe that we can offer further benefits to legitimate purchasers by offering free updates when appropriate. If we ever need to modify existing content or add entire new sections, we can send an email blast to all purchasers which will allow them to download a new copy with all updates for free. Since each copy of this work is watermarked with both a visible and hidden unique code, we can block updates from those who publish the book without consent. Overall, we want to reward those who support us with a searchable, copyable, updatable, and printable document, even at the risk of losing half of our sales to the pirates. With Extreme Privacy: Mobile Devices , I present a new approach to our tutorials. It is not a replacement for Extreme Pr ivacy (the printed book). Please consider it a much more thorough supplement about mobile devices. My hope is that this could become a series of shorter volumes which each focus on one specific topic. This would allow people to only purchase the content which they need at a more affordable price. I think it would also allow us to publish content more rapidly, as we can focus our efforts on one area at a time as needs arise, instead of reserving content for a potential future release. Free updates are also a win for everyone. Time will tell if this works. For now, I present this new PDF solely about building the optimal mobile device. 2 INTRODUCTION I believe the most vital step toward obtaining an advanced level of privacy and security is replacing your mobile device and cellular account. Some privacy enthusiasts will tell you that you cannot possess a cellular telephone and still expect any privacy. They have a point, but that is unrealistic. If I informed my clients during an initial meeting that they could never use a mobile app again or send a text message while on the run, I would have no more business. My goal is to allow you to enjoy the benefits of technology while providing minimal data to the companies that benefit most from your usage. Think about mobile devices from a privacy perspective. We purchase our phones with our own money, pay a monthly fee for cellular connectivity, and carry it everywhere we go. We create and log in to a Google or Apple account for convenience without consider ing the many ways our data will be abused. The devices are in constant communication with various cellular towers, and their precise location is documented within permanent storage. Apple or Google is collecting information about us and our usage every minute, and then sending the data to their servers for their own analysis and benefit. Our cellular providers allow the software on our phone to pass location data to third parties. Who cares? I do, and so should you. Consider the following. Any court order demanding your full activity will immediately disclose your location history and all communications. A log of your phone calls and text messages are archived forever and could display an interesting story based on your communication patterns. Your location history could identify your home address, the other places you spend the night, and people you visit. It might identify your habit of speeding down the interstate or identify the organizations with which you hold a membership. However, it gets worse. A geo fence warrant which has no association with you could disclose your location details even though you were never a suspect. These broad demands provide a dump of data to investigators which identifies any device within an area where a crime occurred. The information is then permanent record within the investigating agency and prone to leaks or FOIA requests. In 2018, Jorge Molina was arrested and held in jail for six days for murder. After receiving a search warrant, Google provided a list of all mobile devices which possessed Google accounts and were l ocated within the area during the crime. Molina’s device was on it; however, he was not the killer. He was never even near the crime. He was released after police identified the true killer, but the damage was done. He still has a public record of being arrested for murder. An employee of Apple, Google, or your cellular provider could also access all of this information with ease. We have seen numerous incidents where employees do bad things for personal gain or revenge. I trust no one. Finally, we must consider the potential for a breach. As I write this, T - Mobile accidently leaked 37 million customer records including full names, phone numbers, 3 home addresses, email addresses, and dates of birth of subscribers. Numerous pr evious breaches and leaks are already publicly available. These databases are then traded, sold, and abused by strangers. They are devoured by marketing agencies. What can be done? I believe we can remove ourselves from these risks. This book will help you create a device which does not send data to Apple or Google. Cellular service will be obtained in an alias name, and it will be affordable. A Google or Apple account will not be required in order to download applications and have full - functionality of the device. A true name and physical address will never be associated with the device or service. You will possess numerous numbers within one device which will a llow you to protect your true cellular number from the threats previously explained. There will be no more concerns about SIM swapping or account takeover. We will all take our privacy back. This entire book is designed for the reader interested in extreme privacy. At times, I will assume that your physical safety is in jeopardy, and that making any mistake is life or death for you. I will treat you like a client who is running from a homicidal former lover that is determined to kill you. I will assume that your adversary is tech - savvy. I will never consider costs of products or services, as your privacy and security are more valuable. I will not sugar coat my opinions or offer less - secure options for the sake of convenience. I will explain every step and will never make assumptions on the reader’s level of technology awareness. This is our entire playbook for every new client’s mobile device. It is comprised of our internal client tutorials and staff handbooks, with extended details provided by myself. It should allow you to create a perfect private and secure mobile device for your needs. I leave nothing out, and include many new strategies previously omitted from Extreme Privacy, 4th Edition I offer one last vital piece of information before we start. I encourage you to generate your own opinions as you read along. You may disagree with me at times, which is ideal. That means you are really thinking about how all of this applies to you. If everyone unconditionally agrees with every word I say, then I am probably not saying anything interes ting. If this book only presented content which no one could dispute, then there was no need for the text. Please read with an open mind and willingness to try new things. Let’s begin. 4 CHAPTER ONE DEVICE SELECTION I should present the bad news now. If you want extreme privacy, you need a new mobile device. Clients often ask me if they can simply factory reset their current phone, and my answer is always no. Consider the following arguments. Assume that you are a ha rdcore Apple user. You have a MacBook laptop and an iPhone device. Every Apple product possesses an embedded serial number. This number is associated with your Apple account. Both mobile and laptop devices constantly communicate with Apple servers, supplyi ng the identifiers associated with your devices. Hard resetting (wiping) an iPhone does not reset the serial number. Apple still knows who you are. Creating a new Apple ID for use on these devices does not help. Apple maintains a log of all Apple accounts connected to any device. A court order to Apple, a rogue employee, or a data breach can immediately associate your ne w account to your old, and all of your accounts to all of your hardware. This includes location data and IP addresses. There is simply no way around this. Apple requires an AppleID account to download free apps to your device. Sneaky. This also applies to most Microsoft and Google products. If you have a stock Android device, Google collect s unique identifiers from the device and attaches them to your account. They also store any telephone numbers associated with the device along with unique identifiers within the modem. Since Google also requires an online account to download from their Play Store, they get to collect information about your usage of their email, voice, photos, YouTube, and other services. Wiping the device and attachin g new cellular service and a new Google account will fool no one who has the authority to take a peek. Therefore, we obtain new equipment. It is time to replace your mobile device. For my clients, I arrive with the new equipment in order to ensure it is not associated to them at the time of purchase. Whenever possible, I pay with cash at an electronics stor e, provide no personal details, and walk out with clean equipment. My image (barely visible under my cowboy hat) is stored on their surveillance system for years, but is not the client’s presence. If you plan to buy new hardware with cash, you may want to find a nominee that does not care about privacy to go in the store and make the purchase on your behalf. This is a bit extreme, but justified by some. During a phone call to an Apple store on my podcast, a manager admitted that every store’s surveillance footage is routed to a central collecting location, and stored for an undetermined time. I assume forever. I also assume facial recognition is applied or will be implemented in the future. Some advocate for buying used devices in order to further confuse the systems that collect user data. I do not endorse this. You never know what you are buying. What if the previous owner was a drug kingpin being monitored by the DEA? A court order 5 to Apple shows the DEA agent that the device is now being used by a new account. They would have the legal authority to secretly monitor you. While that would be a very rare occurrence, the possibility of purchasing stolen equipment is much more feasible. If the police show up at your door because your cellular carrier provided the current location of a stolen phone, you will be required to iden tify yourself. Your name and home address will be included in a report, which is public information with a simple FOIA request. You will be able to explain the purchase, but the damage will be done. All of your hard work at anonymity will be ruined. The most likely negative outcome from purchasing used equipment is a locked device. It could be stuck within a contract through a specific carrier and you will not be able to activate any service until that debt is paid. If this sounds impossible to you, read some negative reviews on Swappa. You will find countless people who purchased a useless locked device because they wanted to save a few bucks. We can prevent these situations by purchasing new equipment from retail stores. The minimal extra cost now provides peace of mind while continuing your privacy journey later. I never purchase devices online because there is an immediate permanent digital trail. Even if I used an alias name for the transaction, the device was delivered somewhere and purchased with a credit or debit card which is attached to a bank account. The seller has documentation of unique identifiers for the device. All of this can be tracked. Cash at a BestBuy or other store is much more private. Fortunately, the devices we will be using are plentiful in retail locations. We should probably have the Apple vs. Google discussion now. There are hardcore Android users reading this who never want to use an Apple product. They refuse to pay the "Apple Tax" by switching over to an overpriced ecosystem. They want control of their devices and the ability to make modifications which Apple would never allow. There are also hardcore Apple users who prefer the shiny visual pleasantries of iOS and would never lower themselves to an Android device. They love the convenience of transitioning an Apple account to a new device every year with very little effort. The data magically shows up every time. I understand the cravings of both sides, and I believe either can be satisfied by the end of this book. I am not an Apple fanboy, but I do believe the iOS operating system and hardware on the Apple platform is more secu re and private than any official default STOCK release by Google (Android). I do not like the constant data transmissions that Apple collects and stores about your device and usage, which I believe is just as bad as the data collection and usage from stock Google products. Fortunately, we can avoid all data collection by both Apple and Google with a custom phone which is explained in a moment. In previous years, I pushed Apple iPhone devices onto my clients since they were the best easily available op tion. Most clients were most familiar with iOS anyway, and very few were willing to adopt something new. Since then, we have witnessed Apple continuously add new data - collection features in effort to enhance the overall iPhone 6 experience. Today, the only phones I provide directly to clients are custom Android devices which are both private and secure. I no longer carry any iPhone or other iOS device and I insist my high - target clients do the same. I would also never consider a stock Android device. The amount of personal data forced to be shared with Apple and Google is too much, even with an "anonymous" user account. Instead, I combine reliable Android hardware with un - Googled Android software to create our best option for privacy and security. After I present these new optimal mobile device strategies, I offer my previous methods of using Apple devices as privately and securely as possible. However, I ask you to read through the entire book before continuing with your Apple device. I believe you will agree that removing yourself from these invasive companies is worth the slight hassle. If you still want to proceed with an iPhone, many of the strategies within the following chapters will still apply, especially regarding DNS, VPN, VoIP, and other technologies. In Extreme Privacy, 4th Edition , I presented four Android paths for consideration. I encouraged readers to consider GrapheneOS as their mobile dev ice operating system, but also explained other options. I walked the reader through custom ROMs, such as LineageOS, since they supported a larger number of devices. I also explained how one could use Terminal commands to modify a stock Android system and disable undesired applications. I even offered an example of building your own Android Open Source Project (AOSP) build and flashing it to a supported device. In this book, I only present one Android consideration: GrapheneOS. This decision will trigger some readers. There are loyal fans of various secure Android systems such as LineageOS, CalyxOS, /e/OS, Cop perheadOS, and others. I have great respect for any community which contributes their work toward our privacy and security. However, I only recommend GrapheneOS to my clients, and it is the operating system I use every day. I also want to eliminate unneces sary complexity of choice by presenting every possible option. However, much like the previous Apple disclosure, much of this book can still be applied to other custom Android - based operating systems. I believe GrapheneOS is the ultimate solution for our needs. It is the only option which meets all of my requirements, including the following. • It is comp letely open - source software which converts a traditional Google Pixel device into a pure native Android environment, including many enhanced privacy and security features, without any Google network services or connections. • It has a large community testing and verifying any changes, and updates are much more frequent than other builds. • It provides only the basics and allows you to customize the software you need. • It has a locked bootloader and does not require root access. 7 • It allows sandboxed Google push services if appropriate for your needs which can easily be disabled or removed completely if desired. • It does not require microG for notifications. All of this, and much more, will be explained later. I carry a GrapheneOS Pixel device with me every day for all communications. It is also my only travel and home device (much more on this later). However, there is no elitism here. Make the best decisions for your own situation. You may prefer another option. Most of this book will apply to any custom un - Googled ROM, but I will only reference GrapheneOS throughout. Take yo ur time, understand the techniques, and make educated decisions about your own mobile device usage. Much of this book will appear very technical, but the final product we create will possess more privacy, security, and anonymity than anything you can buy off a shelf. I assure you that anyone is capable of completing this process, regardless of your under standing of the technology. I will explain everything, somewhat painfully at times, to make sure no detail is omitted. GrapheneOS eliminates all data collection by Google, and introduces "Full Verified Boot" within a minimalistic custom operating system. Verified Boot ensures all executed code comes from a trusted source, such as GrapheneOS. It establishes a full chain of trust from the hardware to the software. During the boot process, each stage is verified for authenticity before data can be accessed. It basically makes sure no one has tampered with the system. Typically, uploading a custom OS to an Android device requires you to unlock and disable this bootloader. After the operating system is installed, the bootloader must remain unlocked in order to use this unofficial build. The unlocked bootloader presents a vulnerability. If I physically took your device; uploaded my own malicious software to it; and then put the phone back, you may not be able to tell. Your data and apps might all look the same, but I could monitor your usage if I modified the OS to do so. This may seem far - fetched until it happens to you. This is where GrapheneOS has an advantage. After installation, you re - lock the bootloader for additional protection. It then detects modifications to any of the operating system partitions and prevents reading of any changed or corrupted data. This protects the device from many attacks. The authenticity and integrity of the operating system is again verified upon each boot. I cannot unlock the bootloader without deleting all personal data encrypted within the device. Your data is safe. Because of this, a Google Pixel device is required to install GrapheneOS. Some may be surprised at that sentence. Yes, I recommend a Google Pixel device. This is because we will completely remove all software included with the device and replace it with better versions. Pixel devices offer superior hardware security capabilities than most Android devices, and a Pixel is required for GrapheneOS. Which device should you purchase? That is a personal choice, but understand your options. At the time of this wr iting (January 2023), the following Pixel devices were supported by GrapheneOS. 8 Pixel 7 Pro Pixel 7 Pixel 6a Pixel 6 Pro Pixel 6 Pixel 5a Pixel 5 Pixel 4a (5G) Pixel 4a Any of these devices could be purchased today and possess GrapheneOS within an hour. However, these are not all ideal options. The 4a, 4a (5G), 5, and 5a will all stop receiving support from Google by the end of 2023. This means that they will also likely stop receiving updates from GrapheneOS. If you possess one of these devices and want to use it for testing, or as a personal device until late 2023, I have no objection. If you are purchasing a new device for long - term use, I highly recommend a 6, 6 Pro, 6a, 7, or 7 Pro. If you are reading this in the summer of 2023, the 7a is probably available. In late 2023, we should see the 8 and 8 Pro’s appear. Which will you choose? Maybe I can help. The "a" versions are considered the affordable options for most users. They are very similar to the flagship releases, but are often slightly limited in features. As an example, the 6 and 6 Pro have better and larger displays; possess more RAM; and include nicer cameras than the 6a. They are also twice the price. If you want a premium camera and top speed, then those flagship models may be appropriate. However, the 6a is much more than sufficient for our needs, and is quite affordable. I purchased a Google Pixel 6a specifically for writing this book for $300, paid in cash at a local BestBuy store during a holiday promotion. Today they can be found for $399. I personally carry a Pixel 6a and it is the default option I provide for my clients. When the 7a’s arrive, I will very likely transition to the updated model. All 6, 7, and future Pixel devices will receive security updates for five years. This also transl ates to the likelihood of five years of GrapheneOS weekly updates. My 6a should be supported until July 2027. Much of my desire for the "a" model is size. They are typically smaller than the flagship options. I prefer a smaller device. I think the 6a is still too large and crave the days when my 4a was top of the line. If the upcoming Pixel 8 possesses a smaller footprint, as rumored to be true, then I would consider that over the "a" series. For now, my 6a meets all of my needs. Once you have identified the appropriate model for your usage, please only consider "unlocked" devices. Some stores will push you toward a device which is designated for a specific carrier such as T - Mobile or Verizon. While there may be a slight financial incentive for this restricted device, it will not work for every tactic presented within this book. By purchasing an unlocked device, you have the freedom to choose your cellular service provider at any time. Later, I present a strategy which allows you to connect to any provider's towers for service, and an unlocked device will be crucial. 9 I would like to remind readers that every mobile device will be replaced with the latest and greatest at some point. The 6a is much more powerful than devices from only a year prior. Please don’t try to constantly chase the fastest and best thing out there. You might drive yourself crazy. The "budget" phone of today is usually better than the flagship of yesterday. Consider your needs. Purchasing t he most expensive device will probably result in wasted processor limits and unused RAM. Unless you constantly play the latest games, take professional photos, or only watch 4K movies on your device, you do not need anything expensive. If you need all of that, you probably will not like our final private and secure device anyway. Most readers in early 2023 will find the 6a to be their best option. Once the 7a is available, consider that device. 10 CHAPTER TWO OS INSTALLATION Once you have obtained the best device for your needs, you are ready to install GrapheneOS. There are two options for installation of GrapheneOS onto your Pixel device. The web installer is the easiest for most users, while the Linux method is most stable for those without a chromium - based browser. I will discuss both. However, the web installer should work for your needs. Prepare the Device Regardless of the installation path you choose, you must first prepare the phone itself. Turn on the Pixel device and dismiss any attempts to enter a Google account. On my new unit, I had to conduct the following. • Click "Get Started", "Skip", then "Set up offline". • Click "Continue" then "Next". • Deselect all options and click "Accept" then "I Accept". • Click "Skip", confirm "Skip", and "Skip" again. Swipe the menu up to find and launch "Settings", then navigate to "System Update" and apply all pending updates. Reboot and continue to apply updates until none are available. Note that your device will require internet access via Wi - Fi to complete the process. This could take some time, especially if this is a brand - new device with Android 12. It is vital to patch the phone to the latest Android build before we proceed. When all updates are applied, conduct the following. • Navigate to "System Update" and apply all pending updates. • Tap "About phone". • Tap "Build number" several times until "Developer mode" is enabled. • Tap the back arrow then tap "System". • Tap "Developer Options". • Enable "OEM Unlocking" and "USB debugging". If "OEM Unlocking" is still greyed out and unavailable, you must conduct a full factory reset before you proceed. I conducted the following. Skip this section if you completed the previous steps. • Remove any fingerprints from "Settings" > "Security" if applicable. • Remove any accounts from "Settings" > "Passwords & accounts" if applicable. • Click "Settings" > "System" > "Reset options" > "Erase all data". • Reboot, enter system, connect Wi - Fi, and wait 2 minutes. • Enable "OEM Unlocking" and "USB debugging" using the previous tutorial. 11 Browser - Based Installation We can now install GrapheneOS. I will begin with Web Installer. From your Windows, macOS, or Linux computer, make sure you have a Chromium - based browser installed. If you have Chrome available, it should work fine. If you do not have Chrome, which I do not due to Google's pr ivacy invasions, download and install Brave Browser (brave.com). This provides the stability of Chromium but lacks most of the invasive software included with Chrome. You can uninstall it when finished if desired (I did). Next, navigate to https://grapheneos.org/install/web and read through the entire page. Once you understand the overall installation process, run through the steps, which are outlined next. Always rely on the official GrapheneOS page for any changes since publication. The following are the steps required at the time of writing this chapter. Make sure you have only one browser open and only one browser tab available. • Turn the device off. • Hold the power and volume down buttons simultaneously. • W hen you see the "Bootloader" menu, release the buttons. • Connect the device to computer via USB cable. • Click the "Unlock Bootloader" button on the GrapheneOS page. • Select your device from the popup menu. • Click "Connect". • Press the volume down button on the device to change options and highlight "Unlock Bootloader". • Press the power button to confirm the choice. • Click the "Download Release" button on the GrapheneOS page. • Allow the appropriate version of GrapheneOS to completely download. • Click the "Flash Release" button. • Allow the process to complete. • Click "Lock Bootloader" on the GrapheneOS page. • Press the volume button on the device to select "Lock Bootloader". • Press the power button to confirm the choice. • Make sure "Start" appears next to the power button and press it. • Allow the phone to boot. This sounds simple, but a lot can go wrong. In my experience, only Chrome - based browsers will reliably complete the process, but the choice of operating system itself should have no impact. Chrome, Chromium, and Brave browsers within Windows, macOS, and Linux should all work the same. Attempts with Safari and Firefox failed for me. A poor - quality USB cable can also ruin the entire process, so use the cable included with the device when possible. Some Windows machines may not have the appropriate drivers for your device. If the phone is not recognized, plug it in and attempt a software update at "Windows Update" > "Check for updates" > "View Optional Updates".
